You're listening to TED Talks Daily, where we bring you new ideas and conversations to spark your curiosity every day. Hello. No, I am not Elise Hu. I'm Manoush Zomorodi. I'm a journalist, an author, a two-time TED speaker, and you might recognize my voice because I host the TED Radio Hour podcast over on NPR. So why am I here? Well, this week, I am taking over from Elise to bring you something a little special, a series of episodes all about how you can live a healthier life in our high-tech era. Because in April, I had the honor of guest curating a session at the TED 2026 conference And I packed it full of speakers whose work I have been obsessed with and who I think will make you think differently about your body, how you use your technology, and what is keeping us human in this digital age.
So every day this week, we are bringing you one of these talks from my session, followed by a conversation with these incredible speakers to go deeper. Really, truly, they are amazing. Let's begin with a feeling, okay? That end of the day, so drained, can barely think, exhausted feeling that comes after spending hours on our devices. Physiologist Keith Diaz knows that feeling.
I was still tired, exhausted actually, but I hadn't used my body at all.
I met Keith in 2023 when I came across research he'd done in his lab at Columbia University Medical Center. This is where he studies how lives spent mostly sitting and looking at screens affects our health.
We are living in the most sedentary era in modern history. And what scientists have found is that being highly sedentary increases your risk of diabetes, cancer, dementia, heart disease, and ultimately, early death. This is true even if you exercise regularly.
Yeah, it's awful. But Keith has spent his career trying to figure out the minimum amount of movement that the human body needs every day so that you don't die an early death. Our teams at NPR and Columbia ended up partnering to see if we could get his research out into the world. We wanted to find out, could people take movement breaks throughout their day and take back their health from their sedentary screen-filled lives. And we ended up creating one of the largest citizen science studies ever. If you follow me on social media, you have probably seen me post about this study. We called it Body Electric. And very recently, I put out a book by the same name, which has these findings at the heart of it.
Keith explains the study and what you need to maintain your body on a daily basis. And then I join him to talk about what it takes to balance our biological needs with all the conveniences of modern life so that we're not living some drained, tired version of ourselves. All that right after a quick break.

And now, our TED Talk end conversation of the day.
My favorite job ever was as a summer camp counselor, where I was basically paid to play games with kids all day. We played capture the flag, running bases, dodgeball, went swimming in the pool every day. And at the end of the day, I'd be tired, but in a good way.
